rendering server group: listing existing servers: %w

Error message

rendering server group: listing existing servers: %w

What it means

In RenderScw, while tagging servers that need updates, the GetServer call for one of the IDs in actual.NeedsUpdate failed. The server could not be fetched before its update tag could be applied; the wrapped error is the SDK response (typically the server vanished or a transient API failure).

Solutions

1. Verify the server ID still exists in the Scaleway console
2. Re-run the apply: the Find phase will recompute NeedsUpdate
3. Check the wrapped error for auth/quota causes
